What are the solutions of the inequality? 12x – 3x + 11 > 4x – (17 – 9x)

OpenStudy (anonymous):

12x -3x + 11 > 4x - 17 + 9x (you have to distribute the negative sign) 9x + 11 > 13x - 17 (combine like terms) 9x > 13x - 28 (subtract 11 from both sides to get the variable alone) -4x > -28 (subtract 13x from both sides) x < 7 (divide 28 by 4, then flip the sign because you're dividing by a negative)
